## Various and Sundry

The math department at Columbia this fall will be hosting three special lecture series, each with some connection to physics (at least in my mind…): Sergiu Klainerman will be lecturing on the proof of nonlinear stability for slowly rotating black … Continue reading

## Various and Sundry

Last week a review of the Mochizuki IUT papers appeared at Math Reviews, written by Mohamed Saïdi. His discussion of the critical part of the proof is limited to: Theorem 3.11 in Part III is somehow reinterpreted in Corollary 3.12 … Continue reading

## ABC on NHK

There will be a documentary broadcast tomorrow in Japan on Mochizuki’s claimed proof of the abc conjecture. I was interviewed for this by the filmmakers last year, but don’t know anything about whether and how that footage will be used. … Continue reading

## Some Math Items

Some math items that may be of interest: Zentralblatt Math has a review of Mochizuki’s IUT papers, by Peter Scholze. Scholze explains the problem with the proof claimed in these papers. For more details, see his manuscript with Stix, or … Continue reading

## ABC is Still a Conjecture

Just a reminder that the abc conjecture is still a conjecture, there is no known valid proof (don’t believe what you might read in an EMS journal). For more about why one attempted proof doesn’t work, see here and here. … Continue reading

## Why the Szpiro Conjecture is Still a Conjecture

There has been a remarkable discussion going on for the past couple weeks in the comment section of this blog posting, which gives a very clear picture of the problems with Mochizuki’s claimed proof of the Szpiro conjecture. These problems … Continue reading
